The two extra "nines" make a big difference in your uptime
As a business user, you want the emails to arrive instantly. So when a business email provider like Google Apps or Microsoft Office 365 offers you a 99.9% uptime guarantee, that could sound like it’s good enough—that is, until you do the math. Because over the course of a year, 99.9% uptime—or “three nines”, in industry terms—adds up to more than eight hours of unplanned downtime.
Look for “five nines”
Compare that to Info Exchange’s Hosted Exchange, that offers a 99.999% financially backed uptime guarantee. This equates to less than 10 minutes of downtime over the course of a year—and, if we should fail to deliver, we’ll compensate you for it. Three nines vs. five nines: it’s a difference that may not seem significant in your decision-making process… until the day your email is down for hours.
